A Connecticut business license gives your Limited Liability Company (LLC) permission to operate in a certain location or within a specific industry.

We can’t walk you through any applicable license applications step-by-step, because every business is unique. But we do provide helpful resources like:

  • information about state licensing rules
  • instructions for researching municipal licenses

And if you want to just hire a company to do the research for you, we have a recommendation below.

Connecticut Business License Requirements

Business License

After you form a Connecticut LLC, you may need to obtain a business license or permit.

Your requirements are determined by the industry you are in and where your Connecticut Limited Liability Company is located.

Because of the large number of industries and all of the municipalities in Connecticut, it’s not possible for us to explain them all. However, you can use the search tools below, call your local municipality, or hire a company for help.

How to get a Business License in Connecticut

You can obtain a business license in Connecticut by applying with the relevant licensing or regulatory agency. The agency you apply with will depend on where your business is located and what business activities it engages in.

The business license application typically requires basic information, such as your LLC name, EIN Number, business address, and contact information. Many also include a questionnaire that asks about your business activity.

There are three main licensing jurisdictions:

  • State licensing
  • Local licensing, such as county, city, township, etc.
  • Federal licensing

Does Connecticut Require a Business License?

That depends on where your business is located, and what it does.

There are two types of state-level business licenses:

  • a general business license
  • and an occupational license

Connecticut General Business License

Some states have a general license requirement, which means all businesses operating in those states must have the license, regardless of what they do.

Although Connecticut doesn’t have a general business license requirement, you do have to register with the Department of Revenue and get a Connecticut State Tax Identification Number.

This state tax ID is required to do business in the state, and is different from your LLC’s federal EIN number.

Connecticut State Tax ID Number

Every business operating in Connecticut must have a State Tax Identification Number.

The Connecticut Department of Revenue Services’ Register Your Business page will guide you through the process. The registration fee is $100.

All new businesses must register using myconneCT. Most types of businesses will file Form REG-1. But you should check the list on the Dept. of Revenue Services Applications page to make sure you don’t need to file additional documents with Form REG-1.

Connecticut Occupational License

Most states have occupational business license requirements. This means a license or permit may be required depending on what your business does or what your occupation is. For example, if you sell used cars, or run a hair salon, you may need an occupational business license. But a license may not be required for other types of businesses.

The Connecticut state government has created a digital business assistant that will walk you through a checklist for your new business. This is designed to help you determine if your Connecticut business needs an occupational license or permit, and which agency to contact about applying for the license.

The License and Permit Center has a list of government agencies that issue business licenses. You should contact the relevant agency directly to find out about the license application process.

Note: Connecticut business licenses are not issued by the Secretary of State. The Secretary of State is responsible for business entity administration, for example Limited Liability Company formation.

Connecticut Industry-Specific Taxes

Connecticut also has some industry-specific taxes. The Department of Revenue has a list of Tax Information for Businesses to help you determine if any of these taxes will apply to your Connecticut LLC. This will depend on what your LLC does (what industry it’s in).

You can also contact the Department of Revenue Services with questions.

How much is a Connecticut Business License?

Connecticut doesn’t have a general business license at the state level, so there are no fees there. However, you must register your LLC with the Department of Revenue Services to get a Connecticut Tax ID. This State Tax ID Registration costs $100.

And your business may need a state-level occupational license or municipal-level license or permit to operate. The filing fee for these licenses will vary depending on where you’re doing business and what industry you’re in. To be honest, we can’t predict your specific Connecticut business license cost.

For example, licenses issued by a county that contains a large city are usually more expensive than licenses in less populated, rural counties. And licenses for regulated industries, like child care facilities, are usually more expensive than generic business licenses.

But your LLC might not need a license or permit at all. So your other Connecticut business license cost could be $0 (not including the $100 State Tax ID fee).

See LLC Cost in Connecticut to learn about all the possible LLC fees.

Municipal Business License

Municipal business licenses can be issued by the city, town, county, parish, township, borough, etc. We refer to all of these as a “municipality” to keep things simple.

There are two types of municipal business licenses:

  • general business license
  • industry-specific license

For example, if a municipality has a general business license requirement, all businesses operating in that municipality must have the license, regardless of what they do.

And if a municipality has industry-specific business licenses, a license or permit may be required depending on what your business does. For example, if you operate a food truck, or run a daycare, you may need an industry-specific municipal business license. Or if you’re purchasing or leasing real estate, you may need a zoning permit.

But a license may not be required for other types of businesses, like making wedding invitation templates or offering marketing consulting.

You can contact your municipality to check on their local licensing requirements:

Connecticut Sales Tax License

If you sell products to consumers in Connecticut, you may need to collect sales tax and file a Sales and Use Tax Return.

If your business activities are subject to sales and use tax, your LLC must register with the Department of Revenue Services.

Note: This requirement will apply whether you sell products online or in a physical location in Connecticut.

You can register for sales tax through myconneCT when you apply for your state tax ID Number.

The Department of Revenue Services has a complete guide for new businesses: Managing Sales Tax.

Or you can contact the Department of Revenue Services directly.

Tip: Save time by hiring an expert. We recommend using TaxJar. They'll help you register for, collect, and pay sales tax.

Do I need any federal business licenses?

Most businesses in Connecticut don’t need a federal business license. However, certain industries do need federal licenses:

If your business…Contact this agency about business licenses
Transports animals, plants or biotechnology over state linesDepartment of Agriculture
Imports or exports animal products, wildlife, or products derived from wildlife (including fish)Fish and Wildlife Service
Fishes commerciallyFish and Wildlife Service
Broadcasts on radio or TVFederal Communications Commission
Makes alcohol and sells it at a retail storeTobacco Tax and Trade Bureau
Makes or sells firearms, ammunition or explosivesBureau of Alcohol Tobacco Firearms and Explosives
Transports cargo by seaFederal Maritime Commission
Transports goods or people by airFederal Aviation Administration

Check out the Small Business Administration’s Licenses and Permits page for a full list of industries with federal license requirements.

If your business isn’t one of these special cases, then the only federal requirements are that your LLC get a Connecticut EIN Number (aka Federal Employer Identification Number) and that you file taxes.

Connecticut Business License FAQs

How much does a business license cost in Connecticut?

Connecticut doesn’t have a general business license for LLCs, so there are no fees there. But the required Department of Revenue Services registration costs $100. This is because every Connecticut business must have a state tax identification number.

If your business has to get an occupational license or municipal (city or county) permit, the fees are hard to predict. Depending on your LLC’s location, and what type of business or industry you’re in, the fee varies.

And you might not need a business license at all!

Unfortunately, we can’t say what your LLC’s business license costs would be, because it depends on several factors and the cost of Connecticut licenses varies.

Is an LLC considered a business license?

No, an LLC is not a business license. They are two completely different things.

An LLC is a type of business structure created by filing a document with the state government.

And a business license is a document that gives a person, or a company, the right to transact business. It doesn’t create an LLC.

Does a Sole Proprietor need a business license in Connecticut?

Sometimes a new business owner chooses to operate as a Sole Proprietorship in Connecticut instead of an LLC.

Even if you’re just trying out a business idea as a Sole Proprietorship, you may still be subject to license requirements at the state and municipal levels. It just depends on what you will be doing, and where you will be operating your business.

Does the Connecticut Secretary of State provide a business license?

No, the Connecticut Secretary of State doesn’t handle licensing requirements. Instead, they manage business entity formation and registration. For example, depending on business entity type, business owners file different paperwork with the Secretary of State to create their business entity.

For more information, or to determine if there is a Connecticut business license cost for your business, we recommend contacting the Connecticut Department of Revenue Services and/or your local government agency. For example, your local county or city government will have information about any local licenses.

  1. Hi,
    I plan to make my own perfume and sell it. I already have an LLC in the state of Connecticut,EIN etc
    My question is in order to sell perfumes specifically in my stats how do I go about it

  2. I have a friend that is just starting up a home heating oil delivery company in Connecticut.
    I am trying to help with some questions, and one is does the owner need a Tradesmen Certification and how would they get that?

  3. Hi Matt. Thanks for all the step-by-step instruction!
    I filed for Connecticut LLC.
    I want to proceed to get EIN (and possibly skip LLC approval phase).
    My first client is asking for my W-9 form.
    Is that the CT Department of Revenue State Tax ID Number?
    Or how do I create the form?
    Thank you.

    • Hi Marianne, you’re welcome! What do you mean by “skip LLC approval phase”? No, a W-9 has nothing to do with your state tax ID number. Form W-9 is a federal form from the IRS. Those who pay your LLC as an independent contractor will send you a 1099 at the end of every January. They request this form, the W-9, so they know how to prepare their 1099. You can download the W-9 from the IRS. See here: IRS: About Form W-9.

      I’m going to assume you are the only Member of your LLC, therefore it’s a Single-Member LLC. By default, Single-Member LLCs are taxed by the IRS like a Sole Proprietor. If that’s the case, here are Form W-9 instructions:
      1. Name (as shown on your income tax return): Enter your full name.
      2. Business name/disregarded entity name: Enter your LLC name.
      3. Check off “Individual/sole proprietor or single-member LLC”.
      4. Exemptions likely don’t apply; can be left blank.
      5 + 6. Enter your LLC’s mailing address.
      7. Optional, may not apply.
      Then enter your LLC’s EIN Number (leave social security number blank), sign your name, and date. Hope that helps!

  4. Hi do i need a sales tax permit if Im registered as a dba. Also do I need any permit or special license to run a carpet cleaning business.

    • Hi Edwin, you’ll need to check with your municipality regarding any special license. Connecticut does charge sales and use tax on some services, but that’s best to check with an accountant on. We don’t specialize in business licenses or sales take. Thanks for your understanding.
